St. Vincent fans should mark their calendars next week as Annie Clark will be subbing for Fred Armisen as the band leader on Late Night. She’ll be on the show 8/11 and 8/12, i.e., Monday and Tuesday. It should be interesting — the band leader is typically just there to support the host, but it’s hard to see Clark not completely stealing the spotlight from Meyers. I mean, did you see her on Letterman?
